Adding Del West valves to your engine means you can drive harder and faster. From the aerospace-grade materials we start with, to the precision machines that form the shape, to the performance-enhancing coatings we apply, our valves are designed each step of the way to endure and excel.

Spring Retainers

All Del West valve guides are manufactured with the necessary tolerances and high quality level so that they can be installed directly into the cylinder head guide bore without additional work.

Each material is matched with an appropriate heat treatment and/or surface treatment to maximize the wear resistance and life of the retainer.

Keepers

Del West keepers are the most reliable in racing. The result is a superior valve-stem-to-keeper-to-retainer assembly. When the fit is correct, there is no relative motion in the assembly. This results in less wear and an extended service life of the mating components.
